'METAL-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 417,084, dated December 10, 1889.

Application filed March 28, 1889. Serial No. 304,438. (No model.)

To all whom it may concern:

Be it known that I, LUCIUs \V. POND, a citizen of the United States, and a resident of Vv'orcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Metal-Planing Machines, of which the following is a speedcation, reference being had to the accompanying drawings, representing such portions of a metal-planing machine as are nec essary to illustrate the nature of my invention and the method of embodying the same, and in which Figure 1 represents a side elevation of a portion of ametal-planing machine. Fig. 2 is a top view of the bed and reciprocating table, a portion of the latter having been broken away in order to disclose the belt-shipping mechanism. Fig. 3 shows one of the shipping-dogs attached to the table in the beginning of its cont-act with the vibrating shipping-levers Fig. 4 represents the same dog during its period of contact with the vibrating shipping-levers. Fig. 5 represents the dog at the close of its period of contact with the vibrating shipping-levers. Fig. 6 shows one of the vibrating shipping-levers detached. Fig. 7 represents the hinged dog in perspective view. Fig. 8 represents a portion of the rigid jaw, and Fig. 9 represents'the adjustable toe attached to the portion of the rigid dog represented in Fig. 8, but shown detached therefrom.

Similar letters refer to similar parts in the different views.

My present invention relates to the shipping mechanism of a metal-planing machine; and it consists in providing means whereby the shipping mechanism may be operated either with a quicker or a slower motion rel atively to the speed of the reciprocating table, to provide means for disconnecting the table and the shipping mechanism upon the reverse motion of the table, and in case separate and independent shipping mechanisms are employed for shipping the driving-belts to so connect the separate shipping mechanisms that they mayboth be operated by hand.

In the accompanying drawings, A denotes the bed; 13, the reciprocating table; C D, the driving-pulleys; E F, loose pulleys; G G, belt-eyes attached to the sliding rods G G II is a hollow spindle journaled in a bearin in the bed of the machine, having attached to its outer end the lever H and to its inner end the radial arm. I1 connected by means of the links H and I1 and the bellcrank lever H with the sliding rod G J is a spindle journaled in the hollow spindle H, and having the lever J attached to its outer end and the radial arm J attached to its inner end and connected by means of the links J and J and the bell-crank lever with the sliding rod G".

To the edge of the reciprocating table 13,1 attach the plate K, ad j ustably attached to the table by means of a bolt a, whose head is held in a T-shaped slot Z) in the edge of the table. A dog K is hinged to the plate K by the pin K having a finger K in position to engage the lever H, and a lateral projection or spur K in position to engage the lever J.

To the edge of the table B, I attach a dog L, similarly adjustable along the edge of the table and having a finger L in position to engage the lever J, and a toe L in position to engage both of the levers H J as the table is moved in the direction of the arrows in Figs. 3 and 4. The toe L has teeth L engaging similar teeth L upon the dog L, and a shallow channel or groove to receive the spur L on the dog L, and the toe L is adjustably at tached to the dog L by means of a bolt LT, screwing into the toe L and passing through the slot L in the dog.

The lever H has a slot N, and the lever J carries a pin N, which enters the slot N, so that after a slight movement of the lever J, by means of the hand-lever N projecting from the hub of the lever, the lever H will be moved by means of the pin'N, causing both of the shipping mechanisms to be operated by means of the hand-lever N As the work is being fed to the cutting-tool the table is moved in the direction of the arrow shown in Fig. 3, and as the dog L is brought toward the vibrating levers H J the finger L is first broughtinto contact with the lever J, operating the sliding rod G"and moving the belt from the driving-pulley O to the loose pulley E, and moving the lever J in advance of the lever H, as shown in Fig. at. At this point the toe L is brought against the lever 11, operating the sliding rod G through ICO the connecting meehanisn'i to carry the belt from the loose pulley E to the tight driving pulley D and reversing the motion of the table, which is caused to move'in the direction As the hinged pulley E onto the driving-pulley G, and a feeding motion given to the table in the direction of the arrows in Figs. and 4 until the dog L is again brought into action and the motion of the table again reversed. As the table is reversed in the direction of the arrow shown in Fig. 1, it is sometimes desirable to continue the motion of the table beyond the point at which the levers H J are acted upon by the dog K, in order to withdraw the work from the cutting-tool in convenient position for adjustment, inspection, or other purposes. This is readily accomplished by lifting the hinged dog K in the position indicated by broken lines at K Fig. 1, allowing the dog to pass over the top of the levers II J. The toe L is vertically adjustable by means of the bolt L and slot L so that it may be made to strike against the levers II J at different distances from the center of the spindle J, causing the angular velocity of the levers to be varied relatively to the speed of the reciprocating table B.

In the accompanying drawings I have shown the vertically-adjustable toe L and the hinged dog K in connection with separate and independent shipping mechanisms; but they can be used equally well with a single shipping mechanism, by which both belts are simultaneously shifted, or with any of the devices for shifting the belts of a metal-planing machine in which a vibrating lever is employed like or similar to the levers H or J.

WhatI claim as myinvention, and desire to secure by Letters Patent, is

1. In a metal planing machine, the combination, with a movable belt-eye and a vibrating lever attached to a spindle journaled in the bed of the machine and having operative mechanism by which it is connected with said movable belt-eye, of an actuating-dog adjustably attached to the reciprocating table, said dog being hinged so that it may be removed from the path of said vibrating lever, substantially as described.

2, In a metal-planing machine, the combination, with a movable belt-eye and operating mechanism comprising a vibrating leverjournaled in the bed of the machine, of a plate K, ad j ustably attached to the edge of the reciprocatin g table, and a hinged dog K, hinged to said plate and so arranged that in the normal. position of said dog it is caused .to strike against said vibrating lever, substantially as described. a

3. In a metal-planing machine, the combination, with a belt-shipping mechanism comprising a vibrating lever journaled in the bed of the machine, of a dog attached to the edge of the reciprocating table and having a vertically-adjustable toe attached thereto, whereby the angular velocity of said vibrating arm is varied relatively to the speed of the reciprocating table by causing said adjustable toe to strike said vibrating lever at varying radial distances, substantially as described.

4;. In ametal-planing machine, the combination, with a belt-shipping mechanism comprising a vibrating lever, substantially as described, of an actuating-dog attached to the reciprocating table of the machine, said dog being vertically adjustable, so as to be made to strike said vibrating lever at different radial distances from its axis of vibration for the purpose of varying the angular velocity of said lever relatively to the speed of the reciprocating table, substantially as described.
